olaims. (onze-s4) i 4This invention relatestoa. stretching device,

or a device for stretching and fitting a flexible member into tight engagement with the surface of another member.A vWhile Vthe Yinvention may 5 have various applications, it particularly is designed for stretching and tting brake linings to brake shoes. Such structures are now commonly used inbrake devices, and one common use of the same is in automobile brakes. and important to havethe brake lining brought into firm and intimate contact with the brake shoe before it is secured to the shoe. Many brake linings are now of the molded type, and are more or less distorted beforejbeing placed on the shoe. It is thus increasingly important tohave some device which will stretch and t the lining or band vtightly to the shoe. Bandsare also now being supplied inlcut lengths just suflicient to fit the length of the shoe, and'it isl desirable to have some device which will stretch and flt these short lengths tothe shoe. i

Itis an object of this invention, thereforato provide a deviceby means of which a brake lining or band canbe Aquickly and easily stretched and pressed into firm engagement with the brake shoe. vI t is a furtherobject of the invention to provide a device by means Vof' which the brake lining or band can be stretched longitudinally over the shoe and pressed into very -I'lrm engagement with -A the surface of the shoe'. f

t is still another .object of ythe invention to provide a device comprising aY pair of swinging arms, together withmeans for engaging the band orlining at rthe ends of these arms and moving thearms apart while the band is pressed against the shoe to draw and press the band 'tightly against the shoe.

It is still another object ofthe invention to provide a device comprising a flexible strip of material such as metal, adapted to'engage the band or lining with Vmeans for bringing the ends ofthe vstrip against the band to press the same against the shoe and then moving they ends of the strip away freni each other to progressively and tightly draw the band into close engagement with the shoe. l i v f r It is still further' an object of the invention to provide a device for drawingland pressing a brake band 'against a shoe by engaging. the band at one pressing the other end of said strip against the band and moving it away' from said point to draw and press the band against the shoe.

.It is another object of the invention to provide a device'comprising ,a pair "offoppositely extend- It iS desirable showing thesame in engagement with point with a ii'exible strip ofY material, and then f ing arms, a member to which the adjacent ends of I said arms are pivoted, a flexible strip of metal -connected to and extending between the remote ends of said arms, a screw carrying said member, a block through which said screw extendsand7 into which it is threaded, together with ineens extending from said block for engaging vaibrake shoe, whereby when said means is engaged in the shoe and said strip placed against, thelining on the shoe, said screw may-be rotated to move `the y a, brake band or lining to a brake shoe, comprising a block, a screw extending through and threaded into the said block, a member carried by said screw below said block, a pair of arms pivoted. to

said member Aat opposite sides thereofandn extending in opposite directions therefrom, a vflatv metal strip secured to and extending between the remote ends of said arms, a pair of members pivoted at either sideof said blockv andv having lower hooked ends adapted to engage `under the edges vof the brake shoe, and a spring for drawing said members together, the upper end of said members being formed as handles or finger pieces for separating said members. .l v

These and other objects and advantages of the, Ainvention will be fully set forth in the following description made in connection with thefaccompanying drawing,vr in which like reference characters referto similar parts throughout the several views,: and in whichz-f.; .-f

Referring to the drawing, a device is shown comprising a block 10 through which extends the screw 11 threaded into said block. Said screw 11 has an operating handle or wheel 12 at its'upper end. The screw has co1lars13 formedat its lower end, between which is disposed the top of a lchannel-plate 14,*said screw thus having a reembraced by lugs 15a formed at the ends of arms 15 also shown as in the form of channel members, said arms extending in opposite directions, and the flanges thereof tapering to a small width at their outer ends. Lugs 14a and 15a are pivotally connected by headed rivets 16. As shown in Figs. 1 and 4, arms 15 are curved, the concave side thereof being downward. A flat and flexible strip of metal 17 extends between theends of arms 15, the same being shown as overlapping the outer end portions of said arms and being secured thereto by headed screws 18. Block 10 is bifurcated at its ends and embraces at each end a member 19 of flat formation, said members 19 extending downwardly from block 10 and having hook portions 19a at their lower ends. The Lupper ends of members 19 extending above block 10 are formed as handles or finger pieces 19h. Members 19 are connected below block 10 totheends of tension coil spring 20. A small bar 21 is secured to the central portion of the strip 1'7 and extends beyond the sides thereof, said bar having a slot 21a. therein through which the lower portions of members 19 extend.

Y In operation, when the band or lining such as shown at 22 in Fig. 1 is to be placed on a shoe,

a portion of which is shown at 23, it will be Ylaid upon the shoe so that its ends are approxi- 191) of the members 19 moved together and the hook portions 19a placed under the flanges 23h 'of the shoe 23. Members 19 are then released and the device is thus connected to the shoe 23. Strip 1'7 will engage the band 22 at its end portions or at the ends of arms 15. The central portion of the strip 17 will be slightly spaced from 'the band. The band will now be accurately adjusted to theshoe laterally, and the operator will turn 'handle 12,'thus moving member 14 downwardly away from block 10 and thus moving 'the adja- 1 cent ends of arms 15 downwardly, causing the outerendsof said arms to move away from each other as they are pressed against the band 22. The pressure of the ends of the strip 17 or the ends of the arms 15 against the band as they move awayfrom each other, givesa stretching movement to the band, and it ispulled down tightly overthe surface 23a. The` movement of the wheel 12 and screw 11 iscontinued untilthe entire surface of the strip ll'comes intolengagement with the top of the band 22 asshown iin now be riveted to the shoe by placing the rivets `24 throughthe properholes in the band 22 andthe holes made in the flanges 23D of the shoe 23. `The band is thus connected to the shoe and is in very tight engagement with the surface thereof. The

device can then be released by unscrewing.V screw 11 and moving the portions 19D of members 19 together to release the hook portion'sflQa. If the y shoe is quite long, the device Acan be moved to two or more places thereon and the band stretched Y tightly down onto the portions of the shoe.

From the above description it is seen'that applicant has provided a very simple 'and yet a pressing it into firm engagement with the shoe.

very efficient device for stretchingv the band and ,arms approximately parallel to the convex survface of said shoe for stretching a brake lining thereon, and causing said'strapto hug said lining downwardly and outwardly towardthe convex l inglthe lining thereon and causing said strap to Band 22- is' now stretched and'drawn "hug said brake shoe in lining pressing engagedown-on the surface 23arand pressed against the samewith great force, so that it is invery tight (engagement with lsaid surface. The band 22 can 1 r 1n combination, a member tapped to form a nut,

l mentioned arms, a strap extending between and and the band is pressed against the shoe so tightly that a very thin article, such as a piece of paper, e

' successful and efficient. Y

1 It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims.
